– for learning EDID
from the display while enforcing stereo output if any
HDTV cannot play surround sound normally
Note for EDID (Extended Display Identification Data) learning
1. Don’t plug in HDMI cable to [HDMI In] when you want to restore default EDID or learn the display’s EDID.
2. Please connect the display which you want to read EDID to HDMI Out so the AT-HD50SS can learn the EDID
information from the connected HDTV.
3. To learn EDID from HDMI display, pull the DIP #1 up and down from OFF to ON, the green light will dim and light
to indicate the EDID learning process is complete. You DON’T NEED to pull up the DIP switch again unless you want to
learn another EDID by pulling DIP switch 1 up and down.
Note
1. If the HDTV shows video without audio, please try to set audio mode to stereo.
2. Factory default: Pin#1-OFF[ ], Pin#2- OFF[ ] for 1080p with stereo.
3. If you encounter any unsolved audio/video output problem during system installation, please turn to Safe Mode
(Pin#1-OFF[ ] & Pin#2-ON[ ]) to enforce the most compatible 720p stereo output for system check.
4. Bypass means the matrix will maintain playing the original format of HDMI signals in video and perhaps audio. By
setting at this mode, the users may encounter compatibility issue among different kinds of HDMI sources and displays.
If you cannot get the audio and/or video output normally at the system installation, please change the DIP switch setting
to default mode or even safe mode to verify the functionality of the device.
5 Set Pin#1 at ON[ ] first then connect the HDMI Input to HDTV through a HDMI cable. Wait for 20 seconds. The
EDID learning procedure will be finished. If you want to learn the EDID from another HDTV, you must set Pin#1 at OFF
first and repeat this procedure.
